Abstract: | Late blight caused byPhytophthora infestans is one of the most important diseases of tomato crops in Emilia Romagna. In total, 7–8 chemical sprays are applied per season to control the disease without taking into account the risk of infection. An integrated warning service for the prediction of tomato late blight was set up in order to define a more rational disease control strategy. As a part of the warning service, a number of sites monitoringPh. infestans airborne sporangia was set up for a timely disease prediction in the regional tomato growing areas. The results of 3 years monitoring ofPh. infestans sporangia are presented. They suggest that concentrations of airborne sporangia rapidly increase 1–2 weeks prior the blight onset in the field. |
